The v6 pump I worked on had two small holes in the restrictor instead of one from the factory. In trying to knock out the restrictor to figure out how to drill it, I ended up puching a hole between the two holes accidently. So I ended up with one large hole. For some reason the restrictor would not come out by lightly tapping it out. It ended up working out just fine.
Good luck
I used a nail that I found on the garage floor to poke mine out...works great so far
